概要

It is said that an increase of the amplitude of the fluctuating pressure and a phase shift of the fluctuating pressure are caused by unsteady cavitation dependent on a wake distribution. These effects of unsteady cavitation on fluctuating pressures result in being a great surface force comparing with one in case of steady cavitation or no cavitation. To make clear "whether the phenomena above mentioned are caused by unsteady cavitation or not", the author has performed the theoretical calculation in replacing a cavity including a blade with bubbles. As a conclusion, the fact that "unsteady cavitation contributes to a great increase of amplitudes of fluctuating pressures and phase shifts of fluctuating pressures" have been clarified qualitatively.
